Justin Bieber was in Grand Rapids, Keanu Reeves was in Detroit...was Johnny Knoxville in Burton?

Everybody's in on the joke now, even BJ's. Their "dancing sandwiches" sign is infamous, and now, they've even painted a mural in homage to their slogan on the side of the building.

The bar/grill, on the corner of Belsay and Lapeer Roads in Burton, also made an appearance on Jackass star Johnny Knoxville's Instagram page yesterday...but why?

Was he there? Was he having a dancing sandwich?

Not likely. The picture is clearly from a meme, with the text cropped out. Then again, it wouldn't surprise us if he WAS there for absolutely no reason, given his career track record.
